Abstract

The present invention provides a capped container for which it goes without saying that adequate sealability of the container interior is ensured even as the cap is fastened on the container using a simple fastening structure and the contents do not leak to the outside of the opening of the container body even during seal-opening as with previous capped containers, but also for which the fastening of the cap to the container is maintained and the contents do not leak even when an unexpectedly large impact acts in the cap release direction. The capped container, which is obtained from a container body that has an external thread formed on the outer circumferential surface of mouth and a cap that has an internal thread formed on the inner circumferential surface to be screwed together with said external thread and that is fitted over and detached from the mouth of the container body by screw-fitting, comprises a first fastening means, which is obtained from cap-side ring-shaped protruding strips that engage with each other between the cap and the container body and which exhibits click-stopping, and a second fastening means, which is obtained from multiple container body-side protruding strips that protrude from the container body and multiple cap-side protruding strips that protrude from the cap and which exhibits click-stopping.

Description

Container with cap

The present invention relates to a container with a cap having a cap that closes an opening formed in the mouth of the container body.

Conventionally, a container with a cap having a cap that closes an opening formed at the mouth of the container body has been widely used as a container that can easily store and take out contents. In addition, in many cases with caps, the cap can be easily opened and closed, and when the cap is closed, the contents stored in the container are fixed to the container and the cap so that they do not leak outside during storage or transportation. Means are provided, and in particular, a certain fastening means is necessary for a container that easily scatters, such as a liquid. For example, a method using a screw is generally known.

When using a screw to fasten the container and the cap, align the screw position between the screw provided outside the opening of the container and the inner screw that engages with the outer screw inside the cap. By rotating one of the container or the cap in a certain direction, the thread is guided in the thread groove and moved in the circumferential direction, and the cap and the container are fastened while moving in the axial direction, In order to maintain the hermeticity inside the container, a packing material is arranged at a part of the contact portion of the two members, and the cap and the container body are screwed together so that the inside of the container is separated from the outside and sealed. The structure is common (not shown).

However, when the cap is fastened only with the screw fastening structure, if vibration or the like is applied to the container after fastening, the frictional resistance of the screw is reduced by the vibration, and the fastening structure of the container and the cap is reduced. Looseness, the sealing performance of the cap and the container deteriorates, and in some cases, the cap may be removed.

For this reason, in order to increase the looseness and friction of the screw, a structure is known in which a plurality of screw threads having different lead angles are arranged to increase the frictional force due to the fastening of the screw, to prevent loosening and to improve the adhesion. Further, in addition to the fastening means using screws, one or both of the cap part and the container main body are elastically deformed by a constant axial pressure, and the concave part is provided at the edge of the cap. It is known that the container has a means for locking and closely contacting the container when the convex ring-shaped ridge of the container enters and is in close contact with each other, or when the convex part gets over one of the convex parts. A mechanism (Patent Document 4) that attaches a convex locking tool to the end of the part so that the screw does not return at the end of the screw, and has an annular ridge at the end of the screwed part. , Ki By preventing the screw from loosening by overcoming the annular ridge by screwing in the cap (Patent Documents 2 and 3), this prevents the cap from loosening and generates play. A container with a cap provided with a locking means by a protrusion (protrusion) in addition to a screw means has been proposed, such as those that can prevent the above (Patent Document 5). There is a problem that the contents are spilled at the time of opening because the contents are blown up to the vicinity of the cap due to externally applied vibration or the like.

As means for preventing such leakage, it is conceivable to take a means such as a method using a double cap or an inner ring having a diameter smaller than the diameter of the container body inside the cap. When used, the spillage of the contents can be prevented. On the other hand, in an operation requiring quick movement such as in an experiment, it is complicated to further remove the cap after opening the cap. Even in the method using a ring, a gap is often generated between the container and the inner ring, and the adhesion may be inferior.

Therefore, the applicant of the present application has proposed a container with a cap that can secure the inside of the container sufficiently while fastening the cap and the container with a simple fastening structure (Japanese Patent Laid-Open No. 2014-997).

As shown in FIG. 1, the container with a cap proposed by the applicant of the present application is a container body 1 in which an outer screw 12 is formed on the outer peripheral surface 111 of the oral head 11, and the outer screw 12 is screwed onto the inner peripheral surface 21. When the cap 2 is put on the mouth 11 of the container body 1, the inner screw 22 is formed and the cap 2 is crowned and detached by screw fitting to the mouth 11 of the container body 1. The container body 1 is a container with a cap in which the opening end 112 of the mouth head 11 is in close contact with the top inner surface 24 of the cap 2, and the container body 1 has a top portion from the end portion of the outer screw 12 on the outer peripheral surface 111 of the mouth head 11. A container main body side annular ridge 13 protrudes on the side, and the container main body side when the crown 11 is screwed into the mouth 11 of the container main body 1 on the top side rather than the end on the top side of the inner screw 22 on the inner peripheral surface of the cap 2. Annular ridge 13 gets over So that it has a so-called click stop mechanism with cap-side annular ridges 23 that engage with each other at a position that can be overcome, and with one-click by means of fastening means by screws and fastening means by annular ridges The cap can be securely fastened to the container body, and it has a much higher sealing performance than conventional containers with caps, and can be opened and closed with one click, making it easy to open and close the cap. For example, in the medical field and the research field, external bacteria and chemical substances such as containers used for temporarily storing collected samples (tumors, blood, tissues, etc.) High sealing performance is required because it is required to prevent contamination of the collected sample and biological hazards caused by scattering of collected samples to the outside. While in being, in terms of the test operability is ideal for use as such a container opening can be performed easily in the cap.

However, the container with a cap proposed by the applicant of the present application is, for example, packed in a state where a large number of containers with a cap are erected and transported under a situation where very large gravity is applied during transportation such as an aircraft. At least when a container or a support member, etc. that are arranged adjacent to each other flies in the vertical direction and collides with the lower end surface of the cap that is covered with the container body, and a large impact is applied that does not assume the cap top direction. There is a concern that the cap may come off when a force is applied to the cap-side annular ridge over the container body-side annular ridge. In order to prevent such a situation from occurring, it is conceivable to strengthen the engagement between the cap-side annular ridge and the container body-side annular ridge, that is, to increase the force to overcome by increasing the height. There is a problem that the opening / closing operation becomes difficult and the convenience is lost.
